Not really sure if i need to post this here. But i picked up an old Alpine 1507
and when i bought it it powered up fine. I took it home to clean it up a bit and when I went to hook it back up the power light comes on with a solid red. None of the other lights come on. Iv checked the resistance of all the "fets" and iv visually inspected both the top and underside of the power supply and amp boards. No visual damage is present. The fan no longer spins either. So iv tracked the issue to being on the power supply board.
But i have no idea where else to look for issues. Id really like to my money not to goto complete waste on this amp. Im convinced whatever is wrong with it can be fixed.
Any help is greatly appreciated

I got the amp to turn on. But it only turns on when i shut the ignition or car off. The music and protection lights are green and the power light blinks twice then holds solid until the amp shuts off. Only when the ignition is turned off. As soon as the headunit is completely shut down the amp shuts off
